GeForce GTX 980 vs Radeon RX 470

Intro

The GeForce GTX 980 features a GPU core clock speed of 1126 MHz, and the 4096 MB of GDDR5 RAM is set to run at 1750 MHz through a 256-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 64 Raster Operation Units.

Compare all that to the Radeon RX 470, which comes with a clock frequency of 926 MHz and a GDDR5 memory speed of 1650 MHz. It also makes use of a 256-bit bus, and makes use of a 14 nm design. It is made up of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Radeon RX 470 118528 Mtexels/sec
Difference: 25600 (22%)

Pixel Rate

The GeForce GTX 980 should be a lot (more or less 143%) more effective at full screen anti-aliasing than the Radeon RX 470, and able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 980 72064 Mpixels/sec
Radeon RX 470 29632 Mpixels/sec
Difference: 42432 (143%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
